Abstract

Un compresor centrífugo que tiene una rueda impulsora montada para la rotacion alrededor de un eje central y un difusor para vaciar el fluido comprimido en una cámara recolectora. Una cámara impelente está ubicada detrás de la cubierta impulsora y series de conductos sin remolino están ubicados del impulsor para colocar la cámara colectora en flujo de fluido en comunicacion con la cámara impelente. Una serie de conductos de flujo de canal están dispuestos en el flujo de salida que deja las puntas de las cuchillas del impulsor bajo condiciones controladas, de tal manera que el fluido inyectado entra el flujo de salida uniformemente y con poca pérdida de energía. Un medio de control ajustable regula el flujo a través de los conductos sin remolino para mantener el flujo total en movimiento a través del difusor relativamente constante bajo condiciones de carga variables.
